Initial results from the Orca 1 exploratory well in Block 20 indicate that the field has a resource potential of 400-700 MMbbl of oil, Cobalt said. Analysis confirmed the existence of a large light oil reservoir and a thin condensate and gas cap in the upper sag section of the well. Oil was also detected in the deeper syn-rift section of the well, the company said.

After casing has been set and the well has been temporarily abandoned, the Petroserv SSVCatarina will move to the Cameia 3 location in Angola’s Block 21.
